SPECIFICATION forming p art of Letters Patent No. 371,517, dated October11, 1857.

Application filed March 19, 1887.

Serial No. 23l,556. (No model.)

To all whom, t may concern: y

Be it known that I, HUGO OPPERMANN, a citizen of the United States,residing in the city and county of Philadelphia, State ofPennsylvania,have invented a new and useful Improvement in Egg-Testers, whichimprovementis fully set forth in the following specification andaccompanying drawings, in which- Figure l represents a side elevation ofan egg-tester embodyingmy invention. Fig. 2 represents a top viewthereof. Fig. 3 represents a vertical section thereof. Figs. 4 and 5represent views of detached portions.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention consists of an egg-tester having a novel support for themirror.

It also consists of an eggtestcr having alamp for illuminating the eggs.

Referring to the drawings, A represents the body of thc egg-tester, thesame being formed of metal or other suitable material, preferably ofconical shape, the top of the body being open and provided with aflaring rim, B, to sustain an egg while being tested. To the side of thebody is secured an eyepiece, O, which is set at an inclination, so thatthe eye may be properly directed tothe mirror D within the body A.

The mirror is supported on the basepicce E, which is removably fitted tothe bottom of the body, and has secured to it apin, E, which is adaptedto enter an L-shaped slot, F, in the body, thus connecting the base andbody by a bayonet-joint.

The mirror is inclined and has its lower end resting on the bottom ofthe base and its high end supported on alip, G, which is eut out of theside of the base. Lips H are also cut out ofthe side of the base andbent down on the mirror, the latter thus being clamped between the lipsG H and prevented from displacement.

Secured to the body A is a lamp, J, whose top is adjacent to the rim Bof the body A, so that the tlame of the lamp may rise sufficiently toilluminate the egg resting on said rim.

vThe conical shape of the body is of advantage,A

as it permits the construction of the lamp J on the side of the body Aand within the line of the base, thereby rendering the device stable andnot liable to overturn or upset..

I claim as new, and desire to secure hy Letters Patent, is*

l. An egg-tester having a conical body with the flaring rim B at the topthereof and the lamp J on the side of the body and within the line ofthe base, and havingits burner adjacent to the said flaring rim,substantially as and for the purpose set forth.

2. An egg-tester composed of the body A, with top opening, B, andinclined eye-piece C at the side of said body, the removable base E,with lip G, and the inclined mirror D, the mirror resting on said lip G,said parts being combined substantially as and for the purpose setforth.
